AUTOMATIC DISK RECORD PLAYER Application filed June 17, 1925. Serial No. 87,667.

This invention relates to improvements in phonographs and other record playing mech anisms, and has for its object to provide a machineof the above named class which will automatically play and successively interchange a plurality of records without attention.

A feature of my presentimprovements is to provide a cabinet of comparatively compact form having three compartments, one to contain the operating mechanism, while the other two are in the form of wells to receive a multiplicity of trays or carriers on which the disk records are supported, one well or compartment, the one nearest the record turntable, being employed to receive old, or used records which are periodically lowered into said 'well by successive mechanical control step movements which occur just after each played record has been lifted from the turntable and conveyed across and over the uppermost empty tray and dropped thereon, after which a new, or unplayed record, with its supporting tray, may be moved across from the opposite well onto and over the uppermost played record and its tray, from which position it is in turn lifted and moved across and over the turntable and dropped I into position for playing, and this operation is repeated over'and over again until all the records contained in the cabinet are played, after which said records may be turned over or reversed, when the automatic mechanism may be again started and by my improved construction, an entire program of entertainment, either in dance, song, or other music may be rendered without attention to the mechanism.

A further feature of my present invention is the provision of means for automatically changing the needle or stylus after each rec- 0rd has been played to insure perfect tones and to preserve the records.

A still further feature of my invention is to provide a novel construction whereby when certain parts are disconnected, the machine may be employed to play disk records in the usual way, that is, the records may be supplied to the turntable and removed therefrom and the tone arm manipulated by hand.

Inthe accompanying drawings I have illustrated'a preferred embodiment of the invention, but the construction shown therein is to be understood as illustrative only, and not as defining the limits of the invention.

. In describing my invention I provide a cabinet A of rectangular form, divided in three separate compartments, the larger one B occupying one end of the cabinet and extending entirely around the other compartments G and D which latter, for the purpose of this description, I will term wells which serve to receive and guide a plurality of disk records 10, each supported ona tray or carrier 11.

At the top, the cabinet A supports the usual tone arm E communicating with the usual internal outlet horn F see Fig. 16.

In the constructionshown, the compartment B contains most of the operating mechanism including a motor 12, connected by Wiring to a snap switch 13 on top of the cabinet, the normally open circuit being closed when a brake shoe 14 is wihdrawn from peripheral conact with the record turntable 15.

The motor is preferably worm geared as at 16 to a short shaft 17 for driving the record turntable shaft 18 through bevel gears 19 20, shown clearly in Fig. 26.

Shaft 17 extends backwardly and carries a male clutch member 21 co-actlngw'ith a female companion member 22 on a cam shaft 23, carrying a number of cams to be presently described.

A conveyor arm 24 is mounted to oscillate over the cabinet and is constituted by a housing 25 having a cross plate 26 provided with an inte ral squared pin 27 received in a correspon ing bore 28 in the upper end of a vertical shaft 29, mounted to rotate in a hearing 30 having a flange 31 which is engaged ;bya turntable catch 32 to prevent arm 24 from lifting.

The lower end of shaft 29 is journalled in a bracket 33, and has a fixed short arm 34 connected by a link 35 to a lever 36, swinging from a bracket 37 and having a roller 38 operating in a groove 39 of a cam 40.

A pair of companion levers 41 are loosely carried on a cross pin'42 passing into the sides of housing 25 of arm 24 and, as shown in Fig.9 of the drawings, normally have their rear ends abutting and their forward ends divergently separated, this position being maintained by a spring 43 the under adjacent corners of the rear ends of said levers being beveled as at 44 see Fig. 11 to form an inverted V shaped guide for one of a pair of wedged spreaders 45 on a cross head 46 forming part of a vertical bar 47 slidable in a guide 48 and provided at the bottom thereof with a roller 49, working in a slot 50, in a horizontally reciprocating plate 51 carried at one end in a guide 52 and supported at the opposite end by a fork 53 which straddles the cam shaft 23 and rests thereon, said slot being cut at an angle to the length of members 47 and 51 to cam the roller 49 upward when the plate 51 is moved to the left in Fig. 11.

The plate 51 also carries a roller 54 to operate in a groove 55 of a record releasing cam 56, which only operates to raise the wedged spreaders 45 to release a record at the end of the delivery swing of the conveyor arm 24 in either direction.

To depress the front hooked ends of levels 41 to engage a record, I employ a lifting head 57 lying ]l1St below the rear ends of said levers, which'is formed integral With a Vertical bar 58 slidable in a guide 59 and provided with a roller 60 at the lower end WOIK- ing in a slot 61 formed in a reciprocating bar 62 said slot being cut at an angle with respect to the length of the bars 58 and 62 and acting to cam the bar 59 and head 57 upward and tilt the rear ends of said levers on pin 42 against the action of a spring 68 when bar 62 is moved to the left in Fig. 10.

Bar 62 rests in a guide bracket 63 at one end and has a fork 64 at the opposite end, and also carries a roller 65, to engage the slot 66 of a record pickup cam 67 and the forlv straddles cam shaft 23 and rests thereon.

The front separated ends of levers 41 have downward extensions 68 tapered at the terminals as at 69 and shouldered as at 70 to form hooks adapted to pass throughthe rec-- 0rd aperture 71 and engage the underface thereof as shown in Fig. 14 to lift and convey v bore 73 is enlarged at its top to form a cham-' ber 77 to allow' the hooks to spread and 'en- .g'age the record after passing down through the aperture 71.

. The automatic means as follows-: I

A bracket' 78 'is made fast to the cabinet i as at7I9 andhas side guides 80 in which a cage 81 is movable up: and down. Thecageres M eeives a block 82 which is slida'cbletherein and which'has a circular-lug 83 on one side and a pin 84 threaded into the top thereof,

which'extends upwardly through av slot 85 in the'top of the cage and through aI.corre-"- :sponding slot 86 in the; cabinet, and at the top of said pin is a nut '87'bearing' on a lever 88 t'o' 'be presently'described. I The bracket 78 hasan arm 89 I in which is pivoted a cam lever 96 connected to the underside-of -cage 81 between apertured ears aforesaid new needle,and at this moment, in

- 91 by across pin 92 and on t'he'other end of lever 90 i sa roller 93 bearing on a cam 94 which operates to force the said cageand record as hereinafterdescribed.

The bottom of the bracket 7 8is formed I with a guideway 95 to receive a slideplate a i I I end, in which the pin 84 operates and is made the lug the'cam shaft 23 and a Mg 99 and alsocar- 96 formed with a vertical fork'97,;straddling 83, Ia horizontal fork 98, straddling ries a roller l00ico-actin-g"with aucaml' 101" which acts'to force blockf82to the further.

end of-eage 81 as shown in Fig.18. I Lever 88 has afslot 102 at its inner free I in two parts 103 and 104 joined by a knuckle I in one direction, a needle or{ stylus 120 con- '.on the'sound' box 115. f

joint 105; The part 104 has an aperture 106 in which apin 107 isfixed, said-pin being passed through spaced ears 108 to support the part 109 of a two part lever 110 which parts are joined bylaknucklejoint 111, the outer part 1120f this lever is a'pertured'to' hold a 'link-ll3'connected :witlian eye 1,14

fined in companion grooves 119 formed-in the ad acent'facesof said jaws:

The automatic means for supplying a fresh I needle or stylus to the sound box after each succeeding record is playedfmay be described as follows I o A needle'holding disk 121 is mounted to rotateon a, post 122 at an angle to the top of the cabinet, and-is provided with peripheral sockets 123 'to receive new' needles 120a which are held in said sockets bydelicate springs 124 and said disk also carries a ratchet 125 on its underface which isIengaged-by a -spring metal stop arm 126 and a push dog 127 pivotally carried on a trip arm 128 back pressed by'a 'spring'129, and the said trip arm arrows in Fig. 4, 5, and 6.

pivots about the post 122, with its free end 130, in the path of movement of the jaw 116 which contactstherewith, to rotate the disk one step, equal to the distance between sockets to present a new needle in position, just as the tone arm starts to swing back or inwardly after the said jaws have taken away afresh needle.

To discard a used needle at near the' end of the outward movement of the tone arm, I employ an ejector plate 131 unitary with a I support 132 attached to the cabinet, said plate being positioned to engage the beveled faces 133 of jaws 116 and 117 to separate them and force out the 'used needle, said plate being elongated as shown, to hold the hinged jaw open until the grooves 119 of the jaws are in vertlcal alinement with the nearest .new

needle 120 held by disk 121 when said jaws will ride 01f the said plate, and close over the the operation of the machine, the roller 93 on lever 90 will ride down onto a lower face 134 of cam 94 after having just passed over the high face 135 thereof, thus permitting the .sound'box 115 by the action ofgravity, to drop slightlfy on its pivot and withdraw the new needle om its socket, and when in this therein, in the return or inward movement of the tone arm and its sound box to the playing position, will have clearance past the ejector :plate support through a loop or bend 136a, formedtherein. It is also when in this osi- 'tion, the u per jaw 116 engages the trip ever 128 at the eginning of the inward movement of the tone arm, to rotate the needle disk one step, as will be readily understood. I The automatic means for lowering the played records into their well or compartment and for simultaneouslyraising the unplayed records 'onestep in their well, to'be successively presented for transfer to the playing turntable, may be described as follows -Journalled in bearings 136,attached to the outer walls of the wellsor compartments C,

and D, are'two opposite pairs of revoluble shafts 137 and 138 which have star wheels 139 and 140 fixed thereto and rotated in step movements by a trip wheel 141 having four equirdistant spurs 142 positioned so that one spur normally lies-in the path of travel of a trip lug 143 on the peripheral edge of a'cam 144, to be hereinafter described.

Each pair ofsha'fts137, 138 are geared one to the other by intermeshed pinions 145. and I the shafts, in pairs, at opposite sides of the wells are given reverse rotation by a crossed chain 146 travelling over sprockets 147 the direction of. rotation being indicated by the -The opposite sides of the compartment D into the compartment to support the succesplane or position, the aws and the new needle are cutout as at 148 to receive spring pressed dogs 149 each having a nose 150 pro ecting sive trays 11, therein as they go upward, to leave clearance for the next incoming tray from compartment C, said nose being formed with a beveled face 151 against which the lower tray impinges when carried upward by star wheels 140 to force the nose out, and after the tray passes, the nose is forced in under the edge thereof as shown in Fig. 5 by a spring 153.

The record supporting trays 11 are preferably of sheet metal each comprising a flat body portion 154 having a circular depressed portion 155 and a central aperture 156. The end edges are curled as at 157 for strength, the side edges being bent down to, form rests 158 and inwardly to provide rounded resting faces 159.

The means for shifting the bottom tray in well C to wellD and the topmost tray on well D over onto the played records in well C simultaneously, may be described 'as follows The cam 144 fixed to shaft 23 has a groove 161 in which a roller 162' on a reciprocating rod 163 operates, see Fig. 1, said rod being attached to an arm 164 fast on vertical shaft 165 journalled in bearings 166, and carrying at the bottom a shift arm 1'67 an d a shorter oppositely directed arm 168 connected by a link 169 to a similar arm 170 on a vertically arranged shaft 171 mounted in bearings 1 72 and fixed to its top portion is another shift arm 17 3 provided with a depending finger 17 3a which engages the side of each successive tray 11. to push them across from well D over and onto the trays and records in well C, and at a predetermined time in the operation of the machine, the cam 144 operates the rod 163 to impart opposite swinging movements to the shift arms to simultaneously transfer or shift a tray from well C to D at the bottom and one from D to C at the op, as hereinbefore described.

The tripping mechanism for throwing in the clutch member 21, to operate shaft 23 through one revolution, at the end of the playing of a record, may be described -as fol 'lows:

A housing 174 fixed to the under face of the cabinet top (see Fig. 2), is provided to receive a frame 175 consisting of top and bottom plates 176 and 17 7 connected by posts 178.

An oscillating segmental gear 179 having an arm 180 is mounted on a pin 181 and meshes with a pinion 182 fixed to a large gear 183, which in turn is in mesh with an idler 184 meshed with a pinion 185 on a tripper shaft 186 supporting loosely a tripper '187 which rests on a leather washer 188 lying on a block 189 pinned to shaft 186 so that when said shaft is rotated, the tripper will be frictionally rotated therewith.

The tripper 187 is formed with a sleeve 190 and has spaced apertured ears 191 between lock which a trip finger 192 is mounted-to swing upwardly on a cross pin 193 said trip finger' .arm is in its set position as shown in Fig. 27.

The said trip arm is preferably of sheet metal and has a head 202 with an apertured side extension 203 and carries an upper lug 204 which bears against a leaf spring 205 and a lower trip lug 206 which is engaged by the extension finger of tripper 187 as will hereinafter appear. a

- The shaft 197 which is constantly rotated while a record is being played, has a single tooth gear 207 fixed to its top. which at every turn of said shaft, engages and imparts a step movement to a gear 207a mounted to freely rotate betweenleather washers 208 mounted on a pin 209, said gear being held against racing by a spring dog 207?). Placed between the upper washer and a head on the pin 209 is a frictionally driven disk 210 having one tooth or lug 211 which when turned in the direction of the arrow. will enter a recess 212 on one arm 213 of a lock member 214 freely mounted on a post 215 and the member also has a curved push arm 216 and a stop finger 217 extending down through an opening in the top plate 176 of the frame 17 5 into the path of swinging movement of the pivoted extension finger 194 of tripper 187 under certain conditions.

At .the bottom of shaft 197 is fixed a gear 218 which carries a trip lug 219 and is in mesh with an idler 220 meshing with a gear 221 on the drum shaft 18 to give constant rotation to lug 219 when a record is playing, for the purpose hereinafter set fort The extension 203 of arm 198 is connected by a link 222 to ashift lever 223 having a pin and groove connection as at 224 with the maleclutch member 21, as clearly shown in Fig. 26 and the arm 180 of segmental gear 179 is connected by a link 225 to a bell crank lever 226 carried on the underside of the cabinet top A, its free arm being slotted at 227, to receive a pin 228 on the slide plate 96 of the tone arm control mechanism.

-The segmental gear has a pin 229 which engages the push arm 216 when the finger 217 is 1n the unlocked position, or out of the path of swing of the tripper finger extension 194 .to throw it into the locked position under certain conditions, and the arm 2130f the lock A spring 236 is provided on the bracket 78 with which the lug 99 on slide bar 96 C011". tacts, at nearly the end of its outward movement and is compressed as in Fig. 18 and acts, after a new needle is taken and at the time earn 101 frees its roller 96 to force the block 82 with pin 84 back toward the turntable carrying the tone arm to a position with the needle just over the outer record oove when the cam 94 will again act and ower the sound box to permit the needle to enter said groove and the playing begins.

In the drawings the cams as'shown are approximately correct, but changes in form may be necessary to obtain perfect timing of the mechanism, and in order to better understand the operation thereof, it is thought advisable to describe the sequence of operations which briefly may be set forth as follows Assuming the parts-to be in the position shown in Fig 1, which is the normal rest position at the end of a record playing operation the operations, in order, follow 1. Cam 94 and its .co-acting mechanism' raises sound box and stylus.

2. Cam 101 and its co-acting mechanism swings tone arm out.

5. am 56 and its co-acting mechanism drops played record.

6. Cam 144 and its co-acting mechanism transfers new record from well D'to well 0.

7. Cam 67 'andits -co-acting mechanism picks up new record.

8. Cam 40 and its co-actin mechanism conveys new recormver turnta le.

9. Cam 56 and its co-acting mechanism drops new record on turntable.

10. Cam 94 and its co-acting mechanism drops needle in outer record groove.

'11. Lug on 'cam '40 and its co-acting'mechanism lowers records in well C and raises them in :12. Lug on clutch member 22 acts to stop A rotation'of cam shaft.

the cam shaft one revolution at the end of the playing of a record and this is accomplished as follows I When cam 101 acts, it-forces the tone arm E around to the dotted line position indicated in Fig. 1 by sliding the bar 96, carrying the pin 84, to the right-to the position indicated in Fig. 18, thus compressing the spring 236 which reacts when a new stylus has been picked up to return the said tone arm to the position when its sound box is over the edge of the record after which the roller 93 of cam 94 drops onto the face 134 thereof permitting the stylus to drop into or engage the outermost groove of the record and the playing starts.

The stylus in following the spiral groove of the record will gradually swing the tone arm inwardly and thus through the pin 84 will draw the slide bar 96 back to the left or toward the starting point and this back movement of the slide bar 96 by reason of its connection through bell crank 226 and linkfinger 194 will engage and ride up the inclined surface 199 of the arm 198 and as its movement continues it will drop ofi the head 202 of said arm back of and away from the path of rotary travel of the lug 219 but this lug will engage the rigid finger 196 .of the tripper and swing it out of its path, after washer 188 will immediately swing the tripper fingers back again until finger extenslon 194 rests against the stop 233 and clear of the oncoming lug 219 when it again comes around, but the said lug will engage the rigid finger 196 again and will again swing it out of its path, after which the frictional drive of shaft 186 will again swing the tripper fingers forward until the one 194 strikes the stop 233 and these oscilatory movements of the tripper are repeated over and over again while the record is playing and until the stylus reaches the innermost groove of the record when the inward swing of the tone arm will cease, thus stopping the backward movement of the bar 96 and through the link I 225, stopping the oscillatory movements of the'segmental gear 179 as well as the tripper shaft 186. At the next rotation of the lug 219 it will, as usual again engage the rigid finger 196 and swing it back, but since-the rotary movement of the tripper shaft 186 has ceased, said tripper will remain in the position as left, thus leaving the lug 195 on finger 192 in the path of the lug 219 as it again comes around which will strike it and force the exshift. lever 223' and throw the male clutchtension finger 194 against thetrip lug 206 thus moving trip' arm 198 around to the position indicated by dotted lines Fig. 27 and forcing the link222 outwardly to" operate the member. 21'in'to engagement with-its companion member .22 to operate the cam shaft 23 V through one turn or revolution, after which .the trip lugs 234'and 235 will cpntact and I -force'the link 222.inward1y to reset the trip arm by reason of the lug 2 04having frictional thrust yielding locking action against the leaf. spring 205. I I

The parts are now again'ready forthe next operation of the horn control mechanism.
